This seems kind of hard but for 9 here is it.
19,26,36,53,65,72 I know my reasoning might be confusing but:
(19 + 7= 26) (26 + 10 = 36) ( 36 + 17 = 53) (53 + 12 = 65) (65 + 7 = 72) I think the pattern is 7, 10, 17, 12.
10: 11,20,30,39,53,63 reason:
(30 + 9 = 39) (39 + 14 = 53) (53 + 10 = 63) So I think the pattern is 9, 14, 10
I hope I helped. You seemed in need for help so... :) and If I got it wrong, let me know.
